Abstract

L'invention concerne une architecture de pipeline partagée pour la prédiction de vecteur de mouvement H.264 et le décodage résiduel, et pour l'intra-prédiction relative à l'entropie de codage arithmétique binaire en fonction du contexte (codage CABAC) et de codage à longueur variable en fonction du contexte (codage CALVC) dans le profil principal et le profil haut, pour les applications standard et haute définition. Chaque opération de prédiction de mouvement et de décodage résiduel pour les images de type I, P et B s'effectue via le pipeline partagé. L'architecture permet d'assurer de meilleures performances et d'utiliser moins de mémoire que les architectures classiques. Elle peut être mise en oeuvre entièrement dans du matériel du type système sur puce ou ensemble puce utilisant par exemple la technologie de matrice FPGA ou les circuits ASIC ou d'autres types de logique personnalisée.
